Intraocular lens
An accommodating intraocular lens (IOL) is provided. The IOL includes an optic having an anterior face and a posterior face. One or more centration lips are disposed directly on the posterior and/or anterior face of the optic or directly on the posterior and/or anterior face of a carrier that holds the optic. Anterior centration lips are configured to center the optic in a lens capsulotomy opening. Posterior centration lips are configured to fixate the optic in a lens capsule and also center the optic in a lens capsulotomy opening.
1. An accommodating intra-ocular lens (IOL) comprising:
an optic having an anterior face, a posterior face, a right side, a left side, an optical axis extending in an anterior-posterior direction, an equator extending in a plane substantially perpendicular to the optical axis, an accommodated state, and an un-accommodated state;
an arcuate sleeve disposed about the equator of the optic and defining a lumen, the sleeve comprising a first sleeve segment and a second sleeve segment;
an arcuate translating arm disposed about the equator of the optic opposite the sleeve, the translating arm comprising a first translating arm segment glidably received by the first sleeve segment and a second translating arm segment glidably received by the second sleeve segment;
a first haptic having a lateral portion with a lateral end and a medial portion with a medial end, the lateral end configured to capture an inner or outer periphery of the lens capsule, the medial end coupled to one of the sleeve or the translating arm;
a second haptic having a lateral portion with a lateral end and a medial portion with a medial end, the lateral end of the second haptic configured to capture the inner or outer periphery of a lens capsule, the medial end of the second haptic coupled to the other of the sleeve or the translating arm; and
wherein in an accommodated state, the first and second haptics apply linear pressure on the translating arm and/or the sleeve in the plane substantially perpendicular to the optical axis, the linear pressure translating to a substantially circumferential force applied to the optic to reduce an equatorial diameter of the optic.
2. The IOL of claim 1 , further comprising one or more centration lips disposed directly or indirectly on the posterior face and/or the anterior face of the optic, the one or more centration lips configured to center the optic in a lens capsulotomy opening.
3. The IOL of claim 2 , wherein the one or more centration lips comprises:
a plurality of centration lips equidistantly spaced and disposed directly on the posterior face of the optic to center the optic in a lens capsulotomy opening and to fixate the optic to a lens capsule.
4. The IOL of claim 2 , wherein the one or more centration lips comprises:
a plurality of centration lips equidistantly spaced and disposed directly on the anterior face of the optic.
5. The IOL of claim 1 , wherein the first haptic and the second haptic each have a substantially J-shaped configuration, the lateral end of the first haptic and the lateral end of the left haptic curving posteriorly towards the medial end of the respective first haptic and the second haptic.
6. The IOL of claim 1 , wherein the lateral portions of the first haptic and the second haptic are ridges.
7. The IOL of claim 1 , further comprising a compressible capsule having a first side and a second side and disposed about the equator of the optic wherein the medial end of the first haptic is in communication with the first side of the compressible capsule and the medial end of the second haptic is in communication with the second side of the compressible capsule.
